$17.98
$11.03
$47.14
____
$76.15

Did I miss anything or is there a site with lower prices?
How can I make the transaction safer?
Thanks

hmm...well if you want really cheap prices you can check out www.futurlec.com they have quite good prices.
but when your searching it doesnt come up with very good results. so try using the item type. eg. instead of 120ohm resistor type resistor and select it from the list that appears. hope this helped you

Let me guess Smash,....you are... 12?

I can make out everything except the digikey cart. If you could just copy and paste each one to here and make a list.

Now I need to purchase a soldering iron, can I find one of those at my local wal-mart?

ed1380 · « **Reply #10 on:** January 18, 2008, 04:11:48 PM »

if you're going to be soldering a good bit. even after you've done teh $50 robot then get a good soldering iron. invest just like you did with the $30 programmer.

another option is to get the $35 arduino from sparkfun. you'll just need so solder on some header pins, and you wont even need the $36 programmer. just a usb b cable

if you do get the aurdino, the source code might need to be changed a bit to use diferent pins

SmAsH · « **Reply #11 on:** January 18, 2008, 04:17:19 PM »

yes it is better to invest if your going to using it alot. i did and my soldering iron has lasted me 6 years still working fine today

ed1380 · « **Reply #12 on:** January 18, 2008, 10:04:17 PM »

op sorry for hijacking your thread.

a thing i'd like to add.
the battery seams pretty expensive. you might want to look around for a better deal.
you can get a 9.6v bat w/ charger for $20 at walmart or toysrus

SmAsH · « **Reply #13 on:** January 18, 2008, 10:31:37 PM »

yea i was starting to wonder about that. then i thought it might come with charger.....

ok whatever you say

but Smash you are avoiding my question , DID YOU BUILD A SONAR BOT. Actually I really need working code or pseudo code

SmAsH · « **Reply #17 on:** January 19, 2008, 08:34:51 PM »

yes i did parcially. i didnt get to the programming stage! god. i was still testing if tracks worked when it fell in the pool!

ed1380 · « **Reply #18 on:** January 19, 2008, 08:36:02 PM »

whats with it now?

how about a pic of it?

IIRC your camera phone can do 1200x800

hold one man

sorry about the comment no offence meant i was just kinding around

airman00 · « **Reply #20 on:** January 19, 2008, 08:43:46 PM »

OK smash , thanks for your honesty , thats what I like around here!

basically you have a tank chassis without sensors or anything

what programming language do you use? ,out of curiosity , I tend to use assembly and BASIC for microcontrollers

and by partially you mean have you interfaced the sonar sensor yet, thats the part I am concerned about...

SmAsH · « **Reply #21 on:** January 19, 2008, 10:31:27 PM »

smashes half complete robot? jk lol vid of tracks (home made) www.freewebs.com/smash-robotics/sonarbot
lol

airman00 · « **Reply #22 on:** January 19, 2008, 10:35:48 PM »

The link is http://www.freewebs.com/smash-robotics/sonarbot.htm
and Smash , the treads are on soooo loosely , they will come off in about 5 minutes, I doubt that they can drive the bot at all in that condition. Buy a tank toy and hack it with tracks attached , or don't use tracks at all!

Remember , think of what sensors you will add to truly make it a robot and not a chassis

SmAsH · « **Reply #23 on:** January 19, 2008, 10:44:36 PM »

yea im trying to find a toy with tracks that has enough space in the middle for the internal stuff like motors. will update if i find anything. and Eric do you have msn? or skype?

ed1380 · « **Reply #24 on:** January 19, 2008, 10:48:00 PM »

you dont need alot of room in the middle. you can build up. just have batteries low in teh middle

SmAsH · « **Reply #25 on:** January 19, 2008, 10:51:41 PM »

lol ill go find a toy "made in china" tank.

izaktj · « **Reply #26 on:** January 21, 2008, 01:25:38 AM »

Well guys thanks for the help =P
so the arduino would be better than the programmer?
I alredy have usb b cable =]
